Function Manual, 09/2009, 6FC5397-1BP20-0BA0
Stop at next reversal point
Signal(s) updated: Cyclic
The oscillation movement is interrupted at the next reversal point.
The oscillation movement continues after the next reversal point.
DBX28.6, DBX28.7
Stop along braking ramp
Signal(s) updated: Cyclic
The axis is decelerated along a ramp, the oscillation movement is interrupted.
The oscillation movement continues without interruption.
DBX28.5, DBX28.7
PLC controls axis
Signal(s) updated: Cyclic
Axis is controlled by the PLC.
The reaction to interface signals is controlled by the PLC by means of the 2 stop bits, other
signals with deceleration action are ignored.
Axis is not controlled by the PLC.
DBX28.5, DBX28.6
Oscillation reversal active
Signal(s) updated: Cyclic
The deceleration period after external oscillation reversal (DB31, ...DBX28.0) is active
No deceleration after external oscillation reversal is active
